Abstract : An object of this invention is to create a stable recirculation zone to hold a piloting flame in a ramjet combustor. The invention is a flameholder of a generally spheroidal configuration formed of two streamlined bodies separated by a gap-forming of two streamlined bodies separated by a gap-forming spacer. The combustible fuel which comes from upstream of the flameholder fills the gap where it is ignited. The gap acts as a piloting zone by continuously igniting the flowing fuel mixture which is replenished by a scavenging process.
